SOLE CLAMP.

This invention is particularly intended to facilitate the repair of shoes when outsoles are to be cemented to shoe bottoms, either as the` only means of fastening or preliminary to subsequent stitching. Itis also applicable when soles are to be applied to new shoes in the process of manufacture.

One object is to provide a clamp which will apply pressure over substantially the entire area of the sole and especially along the edge,

and which will be applicable to a considerable range of lengths, widths and contours of shoes. Further objects are to provide a clamp, one plate of which bears against the l5 inner side of the shoe bottom and which is readily applied and removed.

In the accompanying two sheets of drawings which form a part of this description,

Figure l'shows a clamp which embodies this invention together with a shoe to which it is applied, in section on the lines I-I of Figs. 2, 4, and 5.

Fig. 2 shows the clamp and shoe in section on the lines IrI-II of Figs. 1, 4, and 5.

Fig. 3 shows the foot of the clamp and pressure plates which bear against the inner side of the shoe bottom.

Fig. 4 shows the shoe from the upper side with the shoe clamp applied.

Fig. 5 shows the shoe from the under side with the shoe clamp applied.

The clamp comprises a connecting member with an upper part 10 and a lower part 11, the two parts being hinged together at a hinge joint 12 midway of the clamp to facilitate setting in place and removal. A cap plate 13 bridges the hinge joint and is secured by screws 14, 15 to both parts of the connecting member for clamping the joint.

The upper part of the connecting member is bent twice at right angles so that its end can enter the shoe. and its end has lateral forks 16, 16 to which a foot plate 17 is attached. This plate has four groups of inter communicating slots 18, 18, and pressure plates 19, 19 underlie each and are adjustably secured to the foot plate by bolts 20, 20 whic pass through the slots. The pressure plates are spread so as to cover the inner side of the shoe bottom as fully as possible.

The under portion of the connecting member is bent at right angles and its end has lateral forks 21, 21 through the ends of which clamp `screws 22, 22 are threaded. The clamp 66 screws are set against an outsole bearing plate 23 the margin of which is within the margin Application led January 7, 1927. Serial No. 159,562.

The contour Y this bearing plate and adjoining its curved i margin is a'T-slot 24.

As the inside pressure plates cannot fully cover the shoe bottom, particularly in the case of a shoe of the welt type the bearing plate which bears against the outsole is not made to wholly cover the outsole, and additional marginal clamps are provided. Each of these comprises an upper jaw 25 and a lower jaw 26. A fork 27 hingedto the lower jaw carries a clamping screw 28', the end of which slides on a cam surface formed on the top of the upper jaw when the fork is folded to or from the clamping position. The lower jaw has a slotted tail 29 which crosses the T-slot in the outsole bearing late, and is` held thereto by a bolt 30 w ich passes through the slotted tail and has its head engaged by the T-slot. A wing-nut 31 is used on the bolt. By reason of the two slots crossing each other, the position of the margin clamp is adjustable longitudinally, transversely and angularly in position so that it can be brought into positlon for proper engagement with the welt and the margin of the outsole.

In using the clamp, cement is first lapplied to the shoe bottom and to the outsole and the outsole is laid on the shoe bottom. The shoe clamp is then set in place, the hinge joint is clamped, and the clamping screws are set up to press the outsole bearing plate against the middle of the outsole. The margin clamps are adjusted in position and 'secured to the outsole a ains't the middle of the outsole. The margln clamps are adjusted in position and secured to the outsole bearing plate and are then closed by the ends of the clamping screws riding on the cam surfaces of the upper jaws. If clamping by this means is insulicient the clamping screws are set up. The clamp is allowed to remain on the shoe for from twenty to thirty minutes usually so as to give the cement the proper time to set.

I claim,

1. A sole clamp for pressing an outsole against a shoe bottom provided with a foot, and a plurality of pressure plates which are adjustably secured to the foot for bearing directly against the inner side of the shoe bottom. I

2. A sole clamp for pressing an outsole against a shoe bottom by engagement with the inner side of the shoe bottom and the outer side of the outsole in which the connecting member of the clamp is provided midway with a hinge joint, means for clamping the joint, and independent means for operating the clamp.

3. A sole clamp for pressing an outsole against a shoe bottom having plates for bearl0\`\ing against the inner side of the shoe bottomand the middle portion of the outsole, and means for pressing the plates towards each other in combination with marginal clamps adj ustably connected to the plate which bears 15 against the middle portion of the outsole.

4. A sole clamp for pressing an outsole against a shoe bottom having plates for bearing against the inner side of the shoe bottom and the middle portion of the outsole, and means for pressing the plates towards each other in combination'with marginal clamps adjustably connected to the plate which bears against the middle portion of the outsole, the connecting means for the marginal clamps consisting of a T-slot in the outsole bearing plate and slotted tails attached to the clam s with clamping bolts which pass through t ie tails and have their heads engaged by the T-slot.
